When a pulse signal is supplied to the base (a) part of the igniter 2, high pressure is generated on the secondary side of the ignition coil 1 when pulse waveform starts to cause discharge in the ignition plug 3. At this time, counter electromotive force is obtained at the primary side (b) part of the ignition coil 1. The electromotive force is peak-hold processed by the peak hold circuit 4 to hld the peak value of the primary counter electromotive force of the ignition coil 1 until the next ignition.

Then the count is increasing, the number of frequency division stage number is increased by 0.5 at one inversion. Thus, the output signal of the circuit 10 is not multiplied and frequency-divided with less number of frequency division and the same frequency division signal equivalent to the case with that of frequency multiplication is outputted.

Filed: 1993-12-15
Abstract: PURPOSE:To perform high sensitivity and high precision three-dimensional measurement of the plasma as a whole by scanning and measuring electron density of plasma in the crossing direction of a sheet-like two-dimensional surface and a sheet surface. CONSTITUTION:Laser beams from a laser oscillator 2 and a variable frequency laser oscillator 3 are mixed and synthesized by a half mirror 4, and a sheet-like laser beam 8 is created through a sheet-like beam magnifier 5. Next, plasma 1 is radiated by this beam 8, and is excited by the beam when a prescribed frequency condition and a wave number condition are satisfied, and an electron plasma wave 1a is generated. A frequency of the wave 1a has the prescribed relationship with electron density of the plasma 1, and the electron density has the prescribed relationship with a refractive index. Thereby, a sheet-like refactive index different area corresponding to the electron density is formed in the plasma of a measurement object, and moves in the scanning direction. On the other hand, since a reference light source 10 radiates a reference beam 12 in the plasma 1 by crossing a sheet surface of the beam 8, the beam passes through the refractive index different area, and a camera 13 observes this transmitted light.

Abstract: PROBLEM TO BE SOLVED: To prevent the metal contact between a housing and a rotating shaft by regulating the relation between bearing clearance and labyrinth clearance. SOLUTION: In a hydrostatic gas bearing device with vacuum sucking mechanism comprising a rotating shaft 1 and a housing 4 for supporting it through hydrostatic gas bearings 3, 3 made of metal, the labyrinth clearance h1 of a labyrinth part R for isolating a vacuum sucking passage (consisting of an intake port 14, a suction groove 9, a suction port 12, and an evacuating port 13) from an exhaust passage for the gas blown out from the hydrostatic gas bearing 3 (consisting of exhaust grooves 8, 10 and an exhaust port 11) is set larger than the radial bearing clearance hb of the hydrostatic gas bearing 3 (h1>hb). Since the hydrostatic gas bearing 3 having high self-lubricating property makes contact with the rotating shaft 1 prior to the metal contact of the labyrinth part R of the housing 4 therewith, seizure or fusion does not occur.
